Abstract
BACKGROUND This study aimed to explore whether serum CXCL8 concentration can be used as a noninvasive marker of subclinical rejection (SCR) after pediatric liver transplantation (pLT). METHODS Firstly, RNA sequencing (RNA-seq) was performed on 22 protocol liver biopsy samples. Secondly, several experimental methods were used to verify the RNA-seq results. Finally, the clinical data and serum samples of 520 LT patients in the Department of Pediatric Transplantation of Tianjin First Central Hospital from January 2018 to December 2019 were collected. RESULTS RNA-seq results indicated that CXCL8 was significantly increased in the SCR group. The results of the 3 experimental methods were consistent with RNA-seq results. According to the 1:2 propensity score matching, 138 patients were divided into the SCR (n = 46) and non-SCR (n = 92) groups. Serological test results indicated that there was no difference in preoperative CXCL8 concentration between the SCR and non-SCR groups ( P > 0.05). However, during protocol biopsy, CXCL8 in the SCR group was significantly higher than in the non-SCR group ( P < 0.001). In diagnosing SCR, receiver operating characteristic curve analysis showed that the area under the curve of CXCL8 was 0.966 (95% confidence interval, 0.938-0.995), sensitivity was 95%, and specificity was 94.6%. In differentiating nonborderline from borderline rejection, the area under the curve of CXCL8 was 0.853 (95% confidence interval, 0.718-0.988), sensitivity was 86.7%, and specificity was 94.6%. CONCLUSIONS This study demonstrates that serum CXCL8 concentration has high accuracy for the diagnosis and disease stratification of SCR after pLT.

Abstract
Objective: To explore the prognostic factors of extracellular NK/T cell lymphoma (ENKTL) treated with pegaspargase/L-asparaginase. Methods: The clinical data of 656 ENKTL patients diagnosed at 11 medical centers in the Huaihai Lymphoma Working Group from March 2014 to April 2021 were retrospectively analyzed. The patients were randomly divided into two groups: a training set (460 cases) and a validation set (196 cases) at 7∶3, and the prognostic factors of the patients were analyzed. A prognostic scoring system was established, and the predictive performance of different models was compared. Results: Patients' median age was 46 (34, 57) years, with 456 males (69.5% ) and 561 nasal involvement (85.5% ). 203 patients (30.9% ) received a chemotherapy regimen based on L-asparaginase combined with anthracyclines, and the 5-year overall survival rate of patients treated with P-GEMOX regimen (pegaspargase+gemcitabine+oxaliplatin) was better than those treated with SMILE regimen (methotrexate+dexamethasone+cyclophosphamide+L-asparaginase+etoposide) (85.9% vs 63.8% ; P=0.004). The results of multivariate analysis showed that gender, CA stage, the Eastern Cooperative Oncology Group performance status (ECOG PS) score, HGB, and EB virus DNA were independent influencing factors for the prognosis of ENKTL patients (P<0.05). In this study, the predictive performance of the prognostic factors is superior to the international prognostic index, Korean prognostic index, and prognostic index of natural killer lymphoma. Conclusion: Gender, CA stage, ECOG PS score, HGB, and EB virus DNA are prognostic factors for ENKTL patients treated with pegaspargase/L-asparaginase.

Abstract
Objective: To evaluate the application value of metagenomic next-generation sequencing (mNGS) in the diagnosis and treatment of pulmonary infection in immunocompromised patients. Methods: A total of 78 patients with immunocompromised pulmonary infection [55 males and 23 females, aged (50.3±16.9) years] and 61 patients with non-immunocompromised pulmonary infection [42 males and 19 females, aged (63.6±15.9) years] in the Intensive Care Unit of the First Medical Center of College of the Pulmonary & Critical Care Medicine, Chinese PLA General Hospital from November 2018 to May 2022 were retrospectively selected. Patients in both groups received bronchoalveolar lavage fluid (BALF) mNGS and conventional microbiological tests (CMTs) while clinically diagnosed with pulmonary infection. The diagnostic positive rate, pathogen detection rate and clinical coincidence rate of the two methods were compared. At the same time, the difference of adjustment rate of anti-infective treatment strategy based on the results of mNGS detection was compared between the two groups. Results: The positive rates of mNGS in patients with pulmonary infection were 94.9% (74/78) and 82.0% (50/61) in the immunocompromised group and the non-immunocompromised group, respectively. The positive rates of CMTs in patients with pulmonary infection were 64.1% (50/78) and 75.4% (46/61) in the immunocompromised group and the non-immunocompromised group, respectively. The positive rates of mNGS and CMTs in patients with pulmonary infection in immunocompromised group showed a statistically significant difference (P<0.001). The detection rates of mNGS in the immunocompromised group for pneumocystis jirovecii and cytomegalovirus were 41.0% (32/78) and 37.2% (29/78), respectively, and the detection rates of Klebsiella pneumoniae, chlamydia psittaci and Legionella pneumophila were 16.4% (10/61), 9.8% (6/61) and 8.2% (5/61) in the non-immunocompromised patients, respectively, which were higher than those of CMTs [1.3% (1/78), 7.7% (6/78), 4.9% (3/61), 0 and 0] (all P<0.05). In the immunocompromised group, the clinical coincidence rates of mNGS and CMTs and were 89.7% (70/78) and 43.6% (34/78), respectively, with a statistically significant difference (P<0.001). In the non-immunocompromised group, the clinical coincidence rates of mNGS and CMTs were 83.6% (51/61) and 62.3% (38/61), with a statistically significant difference (P=0.008). In the immunocompromised group, according to the results of the etiology of mNGS, the adjustment rate of anti-infection treatment strategy was 87.2% (68/78), while in the non-immunocompromised group, the adjustment rate of anti-infective treatment strategy was 60.7% (37/61), with a statistically significant difference (P<0.001). Conclusion: In patients with immunocompromised pulmonary infection, mNGS has more advantages than CMTs in diagnostic positive rate, diagnosis rate of mixed infection, pathogen detection rate and guidance of anti-infection treatment strategy adjustment, which is worthy of clinical promotion and application.

Abstract
BACKGROUND Capecitabine (CAP) is a classic antimetabolic drug and has shown potential antirejection effects after liver transplantation (LT) in clinical studies. Our previous study showed that metronomic CAP can cause the programmed death of T cells by inducing oxidative stress in healthy mice. Ferroptosis, a newly defined non-apoptotic cell death that occurs in response to iron overload and lethal levels of lipid peroxidation, is an important mechanism by which CAP induces cell death. Therefore, ferroptosis may also play an important role in CAP-induced T cell death and play an immunosuppressive role in acute rejection after trans-plantation.
AIM To investigate the functions and underlying mechanisms of antirejection effects of metronomic CAP.
METHODS A rat LT model of acute rejection was established, and the effect of metronomic CAP on splenic hematopoietic function and acute graft rejection was evaluated 7 d after LT. In vitro, primary CD3+ T cells were sorted from rat spleens and human peripheral blood, and co-cultured with or without 5-fluorouracil (5-FU) (active agent of CAP). The levels of ferroptosis-related proteins, ferrous ion concentration, and oxidative stress-related indicators were observed. The changes in mito-chondrial structure were observed using electron microscopy.
RESULTS With no significant myelotoxicity, metronomic CAP alleviated graft injury (Banff score 9 vs 7.333, P < 0.001), prolonged the survival time of the recipient rats (11.5 d vs 16 d, P < 0.01), and reduced the infiltration rate of CD3+ T cells in peripheral blood (6.859 vs 3.735, P < 0.001), liver graft (7.459 vs 3.432, P < 0.001), and spleen (26.92 vs 12.9, P < 0.001), thereby inhibiting acute rejection after LT. In vitro, 5-FU, an end product of CAP metabolism, induced the degradation of the ferritin heavy chain by upregulating nuclear receptor coactivator 4, which caused the accumulation of ferrous ions. It also inhibited nuclear erythroid 2 p45-related factor 2, heme oxygenase-1, and glutathione peroxidase 4, eventually leading to oxidative damage and ferroptosis of T cells.
CONCLUSION Metronomic CAP can suppress acute allograft rejection in rats by triggering CD3+ T cell ferroptosis, which makes it an effective immunosuppressive agent after LT.

Abstract
Objective: To investigate death and attrition in HIV-infected children under initial antiretroviral therapy (ART) and associated factors in Guangxi Zhuang autonomous region. Methods: This retrospective cohort study was conducted in HIV-infected children under initial ART in Guangxi from 2004 to 2019, data from ART information system of National comprehensive AIDS prevention and treatment information system. Cox proportional hazards models were used to assess factors associated with the death and attrition. Results: In 943 HIV-infected children, the overall mortality and attrition rates were 1.00/100 person-years and 0.77/100 person-years, respectively. The mortality and attrition rates within the first year of ART were 3.90/100 person-years and 1.67/100 person-years, respectively. The cumulative survival rate during the first, second, fifth and tenth year after ART was 96.14%, 95.80%, 93.68% and 91.54%, respectively. Multivariate Cox proportional hazards models results showed that being female (aHR=2.00, 95%CI: 1.17-3.40), CD4+T lymphocytes (CD4) counts before ART <200 cells/μl (aHR=2.79, 95%CI: 1.54-5.06), weight-for-age Z score before ART <-2 (aHR=2.38, 95%CI: 1.32-4.26), hemoglobin before ART <80 g/L (aHR=2.47, 95%CI: 1.24-4.92), initial ART with LPV/r (aHR=5.05, 95%CI: 1.15-22.12) were significantly associated with death; being female (aHR=2.23, 95%CI: 1.22-4.07) and initial ART with LPV/r (aHR=2.02, 95%CI: 1.07-3.79) were significantly associated with attrition. Conclusions: The effect of ART in HIV-infected children in Guangxi was better, but the mortality and attrition rates were high within the first year of treatment. It is necessary to strengthen the training in medical staff and health education in HIV-infected children and their parents in order to improve the treatment effect.

Abstract
Objective: To analyze the early outcome of one-stage hybrid technique in the treatment of Stanford type-A aortic dissection involving the arch and compare its therapeutic efficacy with the classical frozen elephant trunk technique (FET). Methods: A total of 106 patients with Stanford type-A aortic dissection involving the arch in Department of Cardiac and Vascular Surgery, 1st Affiliated Hospital of Soochow University from October 2015 to October 2019 was collected. All patients in this group were treated with one-stage hybrid technique (modified arch debranching technique) without deep hypothermia circulation. Meanwhile, 30 patients with Stanford type A dissection involving the arch who underwent FET from January 2014 to September 2015 were collected. The therapeutic effects of the two surgical methods were analyzed and compared. Results: The age [M (Q1, Q3)] of 106 patients in hybrid group was 49.0 (40.0, 55.0) years, including 89 males and 17 females. The age [M(Q1, Q3)] of 30 patients in FET group was 49.5 (41.5, 65.3) years, including 24 males and 6 females. The time [M(Q1, Q3)] of using ventilator in hybrid group was 56.0 (38.0, 72.0) h, which was shorter than 127.0 (92.0, 145.0) h in FET group (P<0.001). The incidence of cerebral infarction in hybrid group was 2.8% (3 cases), which was lower than 13.3% (4 cases) in FET group (P=0.042); the incidence of postoperative renal insufficiency in hybrid group was 7.5% (8 cases), which was lower than 23.3% (7 cases) in FET group (P=0.023); the ICU time [M (Q1, Q3)] in hybrid group was 8.0 (6.0, 10.0) d, which was shorter than 14.0 (8.3, 24.0) d in FET group (P<0.001). Conclusion: Compared with FET, one-stage hybrid technology is safer and more effective in the treatment of Stanford type A aortic dissection involving the arch. Its short-term therapeutic efficacy appears good.

Abstract
BACKGROUND Enteric anastomotic (EA) bleeding is a potentially life-threatening surgical complication associated with enteric anastomosis during simultaneous pancreas and kidney transplantation (SPKT).
AIM To investigate whether suture ligation (SL) for submucosal hemostasis during hand-sewn enteric anastomosis could decrease the morbidity of early EA bleeding in SPKT.
METHODS We compared the outcomes of 134 patients classified into SL (n = 44) and no SL (NSL) groups (n = 90). This study adheres to the declarations of Istanbul and Helsinki and all donors were neither paid nor coerced.
RESULTS During the first postoperative week, the EA bleeding rate in the SL group was lower than that in the NSL group (2.27% vs 15.56%; P = 0.021); no relationship was found between EA bleeding and donor age, mean pancreatic cold ischemia time, platelet count, prothrombin time international normalized rate, activated partial thromboplastin time, and thrombin time. Anastomotic leakage was observed in one case in the SL group at postoperative day (POD) 14 and in one case at POD 16 in the NSL group (P = 0.754). No significant difference was found between the two groups in the patient survival, pancreas graft survival, or kidney graft survival.
CONCLUSION SL for submucosal hemostasis during hand-sewn enteric anastomosis in SPKT can decrease the morbidity of early EA bleeding without increasing the anastomotic leakage rate.

Abstract
This study aimed at probing into the function of muscone in ameliorating myocardial ischemiareperfusion (I/R) injury and exploring the underlying mechanism. To analyze the function of muscone, H9c2 cardiomyocytes were treated with hypoxia/reoxygenation (H/R) and Sprague-Dawley (SD) rats were treated with left anterior descending (LAD) of the coronary artery ligation for 30 min and reperfusion for 2 h to induce myocardial I/R injury. Quantitative real-time polymerase chain reaction (qRT-PCR) and Western blot were used to detect the expression of SIRT3. MTT assay and TUNEL assay were performed to investigate H9c2 viability and apoptosis, respectively. ELISA was employed to determine the expressions of inflammatory cytokines TNF-α, IL-6 and IL-1β, and myocardial injury markers CK and LDH. Oxidative stress markers MDA and SOD, and ROS expression levels were also detected. SIRT3 inhibitor 3-TYP was used to further confirm whether muscone worked via the augmentation of SIRT3. Herein, we found that muscone significantly inhibited inflammation and oxidative stress in H9c2 cardiomyocytes in a dose-dependent manner. H9c2 viability was promoted by muscone while apoptosis was inhibited. In SD rats, pre-treatment of muscone alleviated I/R injury-induced cardiac function dysregulation and left ventricle remolding. Furthermore, muscone increased SIRT3 expression at both mRNA and protein levels. With 3-TYP inhibiting SIRT3, the protective effects of muscone in H9c2 cardiomyocytes and SD rats were all significantly alleviated. In summary, muscone can attenuate inflammation, oxidative stress and cardiomyocytes injury in H9c2 cells treated with H/R and alleviate myocardial I/R injury of SD rats, which are dependent on SIRT3.

Abstract
BACKGROUND The most effective treatment for advanced cirrhosis and portal hypertension is liver transplantation (LT). However, splenomegaly and hypersplenism can persist even after LT in patients with massive splenomegaly.
AIM To examine the feasibility of performing partial splenectomy during LT in patients with advanced cirrhosis combined with severe splenomegaly and hypersplenism.
METHODS Between October 2015 and February 2019, 762 orthotopic LTs were performed for patients with end-stage liver diseases in Tianjin First Center Hospital. Eighty-four cases had advanced cirrhosis combined with severe splenomegaly and hypersplenism. Among these patients, 41 received partial splenectomy during LT (PSLT group), and 43 received only LT (LT group). Patient characteristics, intraoperative parameters, and postoperative outcomes were retrospectively analyzed and compared between the two groups.
RESULTS The incidence of postoperative hypersplenism (2/41, 4.8%) and recurrent ascites (1/41, 2.4%) in the PSLT group was significantly lower than that in the LT group (22/43, 51.2%; 8/43, 18.6%, respectively). Seventeen patients (17/43, 39.5%) in the LT group required two-stage splenic embolization, and further splenectomy was required in 6 of them. The operation time and intraoperative blood loss in the PSLT group (8.6 ± 1.3 h; 640.8 ± 347.3 mL) were relatively increased compared with the LT group (6.8 ± 0.9 h; 349.4 ± 116.1 mL). The incidence of postoperative bleeding, pulmonary infection, thrombosis and splenic arterial steal syndrome in the PSLT group was not different to that in the LT group, respectively.
CONCLUSION Simultaneous PSLT is an effective treatment and should be performed in patients with advanced cirrhosis combined with severe splenomegaly and hypersplenism to prevent postoperative persistent hypersplenism.

Abstract
During the process of human islet isolation a cascade of stressful events are
triggered and negatively influence islet yield, viability, and function,
including the production of proinflammatory cytokines and activation of
apoptosis. Carbon monoxide-releasing molecule 2 (CORM-2) is a donor of carbon
monoxide (CO) and can release CO spontaneously. Accumulating studies suggest
that CORM-2 exerts cytoprotective and anti-inflammatory properties. However, the
effect of CORM-2 on islet isolation is still unclear. In this study, we found
that CORM-2 pretreatment significantly decreased the expression of critical
inflammatory genes, including tissue factor,
intercellular adhesion molecule-1,
chemokine (C-C motif) ligand
2, C-X-C motif chemokine 10, Toll-like
receptor 4, interleukin-1β,
interleukin-6, and tumor necrosis factor-α
(TNF-α). The isolated islets of the CORM-2 pretreatment
group showed reduced apoptotic rate, improved viability, and higher
glucose-stimulated insulin secretion, and functional gene expression in
comparison to control group. Importantly, CORM-2 pretreatment prevented the
impairment caused by TNF-α, evidenced by the improved glucose-stimulated index
and transplantation outcomes. The present study demonstrated the
anti-inflammatory property of CORM-2 during human islet isolation, and we
suggest that CORM-2 pretreatment is an appealing treatment to mitigate
inflammation-mediated islet dysfunction during isolation and culture ex vivo and
to preserve long-term islet survival and function.

Abstract
Objective: Although single port laparoscopic surgery has achieved good clinical results, many surgeons are discouraged by the difficulties of operation, conflict of instruments, lack of antagonistic traction, and straight-line perspective. Therefore, some surgeons have proposed a single incision plus one hole laparoscopic surgery (SILS+1) surgical method. This study explored the safety and feasibility of SILS+1 for radical resection of colorectal cancer. Methods: A descriptive cohort study was carried out. The clinical data, including the operation, pathology and recovery situation, of 178 patients with colorectal cancer undergoing SILS+1 at Department of General Surgery, Nanfang Hospital, Southern Medical University from March 2018 to January 2019 were prospectively collected and retrospectively analyzed. Clavien-Dindo criteria was used for postoperative complication evaluation and visual analog scale was used for pain standard. Follow-up studies were conducted through outpatient service or telephone and the follow-up period was up to May 2019. Results: A total of 178 patients with colorectal cancer underwent SILS+1, including 111 male patients (62.4%) with an average age of 59 years. Eleven (6.2%) patients received added 1-3 operation ports during operation, and 1 patient was converted to open surgery due to ileocolic artery hemorrhage. The operative time was (135.2±42.3) minutes. The intraoperative blood loss was (34.6±35.5) ml. The number of harvested lymph nodes was 33.1±17.6. The distal margin was (4.7±17.8) cm. The proximal margin was (10.2±5.3) cm. Operation-related complications were observed in 16 patients (9.0%) within 30 days after the operation, of whom 6 had Clavien-Dindo III complications (3.4%). The postoperative pain scores were lower than 3. The average postoperative hospital stay was (5.6±2.6) days. Three patients (1.7%) returned to hospital within 30 days after operation due to intestinal obstruction and infection around stoma. The cosmetic evaluation of all the patients was basically satisfied. Conclusion: SILS+1 is safe and feasible in the treatment of colorectal cancer, and can reduce the postoperative pain.

Abstract
Objective: To analyze the effects of HIV non-occupational post-exposure prophylaxis (nPEP) in men who have sex with men (MSM) in Nanning and Liuzhou, Guangxi Zhuang Autonomous Region. Methods: Participants were recruited through community publicity and advocacy under a "Trinity" approach among non-governmental organizations (NGO), CDCs/hospitals and pharmacies. Basic information, drug taking and follow-up tests of participants who had enrolled for 28 days of the research were collected. Descriptive statistics were used for data analysis. Results: From September 2017 to March 2019, a total of 213 MSM cases consulted for nPEP service, 159 of them were eligible for nPEP, and 154 were enrolled in the study for drug taking. For 132 cases enrolled in the study for 28 days and above, 118 completed the 28-day course of antiretroviral therapy (ART), while 10 failed to complete the 28-day course of ART, and 4 could not be confirmed whether completed the full course of ART due to loss of contact. For those who completed 28-day course of ART, 94.1% (111/118) and 75.4% (89/118) respectively received HIV tests at 4-6 weeks and 3 months after exposure, the results were all HIV negative. Conclusion: Under the "Trinity" approach, taking antiviral drugs earlier after HIV non-occupational exposure can effectively reduce the risk of HIV infection and to some extent, reduce the new infection cases.

Abstract
Objective: To understand the characteristics and associated factors of newly reported HIV/AIDS cases with non-marital or non-commercial heterosexual transmission, in Guangxi Zhuang Autonomous Region (Guangxi), 2015-2018. Methods: Information of newly reported HIV/AIDS cases aged ≥18 years in Guangxi between 2015 and 2018 was collected from the National Comprehensive HIV/AIDS Information System. Unconditional logistic regression model was used to access those factors that were associated with HIV infections through non-marital or non-commercial heterosexual contact. Results: Between 2015 and 2018, a total number of 35 497 HIV/AIDS cases, aged ≥18 years were newly reported in Guangxi. Among them, 32 648 (92.0%) were infected heterosexually while 10 500 were infected through non-marital or non-commercial heterosexual behavior. Non-marital or non-commercial heterosexual transmission accounted for 29.6% (10 500/35 497) of the newly reported HIV/AIDS cases, and 32.2% (10 500/32 648) of those with heterosexual transmission. Males counted for 53.5% (5 617/10 500) of non-marital or non-commercial heterosexual transmission and males to females ratio was 1.2∶1 (5 617∶4 883). Those married or had regular sexual partners counted for 55.9% (5 873/10 500). Commercial heterosexual transmission appeared the main mode of HIV transmission for males (64.4%,16 516/25 633) while main mode for females was non-marital or non-commercial heterosexual transmission and counted for 49.5% (4 883/9 864). Results from the multivariate logistic regression analysis showed that adjusted OR of female HIV/AIDS infected HIV via non-marital or non-commercial heterosexual transmission, was 3.98 times (95%CI: 3.78-4.20) hight than that of males. Among the group aged<50 years and the aged 50-59 years, the adjusted ORs were 1.35 times (95%CI: 1.27-1.44) and 1.13 times (95%CI: 1.05-1.21) hight than that of aged ≥60 years. Those who were single/divorced/widowed, the adjusted OR was 1.53 times (95%CI: 1.45-1.61) hight than that of those married/regular partners. Those with junior high school education, high school education and above the adjusted ORs were 1.22 times (95%CI: 1.16-1.29) and 1.18 times (95%CI: 1.10-1.27), compared to those only with education levels of primary school or below. Conclusions: The number of HIV/AIDS cases via non-marital or non-commercial heterosexual transmission accounted for nearly 30.0% of all the routes of HIV transmission in Guangxi, 2015-2018. Female, aged<60 years old, single/divorced/widowed and having had junior and above high school education etc., appeared as risk factors on non-marital or non-commercial heterosexual transmission, among newly reported HIV/AIDS in Guangxi.

Abstract
BACKGROUND Donation after circulatory death (DCD) liver grafts have a poor prognosis after transplantation. We investigated whether the outcome of DCD donor organs can be improved by heme oxygenase 1 (HO-1)-modified bone marrow-derived mesenchymal stem cells (BMMSCs) combined with normothermic machine perfusion (NMP), and explored its underlying mechanisms. METHODS BMMSCs were isolated, cultured, and transduced with the HO-1 gene. An NMP system was established. DCD rat livers were obtained, preserved by different methods, and the recipients were divided into 5 groups: sham operation, static cold storage (SCS), NMP, BMMSCs combined with NMP, and HO-1/BMMSCs combined with NMP (HBP) groups. Rats were sacrificed at 1, 7, and 14 days after surgery; their blood and liver tissue samples were collected; and liver enzyme and cytokine levels, liver histology, high-mobility group box 1 (HMGB1) levels in monocytes and liver tissues, and expression of Toll-like receptor 4 (TLR4) pathway-related molecules were evaluated. RESULTS After liver transplantation, the SCS group showed significantly increased transaminase levels, liver tissue damage, and shorter survival time. The HBP group showed lower transaminase levels, intact liver morphology, prolonged survival time, and decreased serum and liver proinflammatory cytokine levels. In the NMP and SCS groups, HMGB1 expression in the serum, monocytes, and liver tissues and TLR4 pathway-related molecule expression were significantly decreased. CONCLUSIONS HO-1/BMMSCs combined with NMP exerted protective effects on DCD donor liver and significantly improved recipient prognosis. The effect of HO-1/BMMSCs was greater than that of BMMSCs and was mediated via HMGB1 expression and TLR4 pathway inhibition.

Abstract
Objective: To explore influence on physical development of children aged 18 months from HIV-positive mothers for prevention mother to child transmission of HIV (PMTCT) in Guangxi Zhuang autonomous region, and provide evidence for the improvement PMTCT program. Methods: This retrospective case control study was conducted in 554 HIV negative infants aged 18 months whose HIV positive mothers had received PMTCT services reported through PMTCT system database from January 1, 2010 to December 31, 2017 and 1 109 healthy infants born in 2017, whose mothers were healthy, in Lingshan, Luzhai, and Hengxian counties, ranking top three counties with high HIV infection prevalence, in Guangxi. PMTCT data and physical development data such as height, weight and head circumference of children aged 18 months were collected. The physical dysplasia in the infants was defined as at least one of the three main indicators of height, weight and head circumference below the normal range. Results: The number of HIV-positive mother and their infants in the case group were 667 and 554 respectively, and the PMTCT rates were 91.15% (608/667) and 96.57% (535/554) respectively. HIV positive rate, mortality rate and mother to child transmission rate of the infants aged 18 months were 1.44% (8/554), 3.07% (17/554) and 1.91% (8/418) respectively, and the physical examination results of the infants aged 18 months showed that the physical dysplasia rate was 30.51% (169/554). Among the 1 109 infants in the control group, the physical dysplasia rate was 9.83% (109/1 109). The difference between the case group and the control group was significant (P<0.01). Conclusion: The PMTCT rates of HIV positive mother and their children were more than 90.00%, respectively. However, poor physical development rate of infants aged 18 months were more than 30.00%. The possible influence of PMTCT on physical development of the infants aged 18 months of HIV positive mother's needs to be further studied.

Abstract
There is a need to improve the quality of donor liver from donation after circulatory death (DCD). The purpose of this study was to investigate the effects and mechanism of normothermic machine perfusion (NMP) combined with bone marrow mesenchymal stem cells (BMMSCs) on the oxidative stress and mitochondrial function in DCD livers. DCD livers were obtained, a rat NMP system was established, and BMMSCs were extracted and identified. The DCD livers were grouped by their preservation method: Normal, static cold storage (SCS), NMP (P), and NMP combined with BMMSCs (PB), and the preservation time was up to 8 h. An IAR20 cell oxidative stress injury model was established in vitro by simulating DCD oxidative stress injury and coculturing with BMMSCs for 6 h. Compared with SCS group, after 6 h in vitro, the PB and P groups had significantly improved liver function and liver histological damage, reduced hepatocyte apoptosis and oxidative stress, improved hepatocyte mitochondrial damage, and increased mitochondrial membrane potential. These indicators were significantly better in the PB group than in the P group. BMMSCs significantly inhibited reactive oxygen species release from the IAR20 cell oxidative stress model in vitro, ameliorated mitochondrial damage, and increased mitochondrial membrane potential level. BMMSCs also downregulated the JUN N-terminal kinase-nuclear factor kappa B (JNK-NF-κB) signaling pathway significantly in the IAR20 cell oxidative stress model and promoted AMP-activated protein kinase (AMPK) activation. We verified that NMP combined with BMMSCs also played the same role in the PB group. NMP combined with BMMSCs could improve liver quality by relieving oxidative stress injury and improving mitochondrial function in rat DCD livers. The mechanism of protective role might involve inhibiting the JNK-NF-κB pathway to reduce oxidative stress and promote AMPK activation, thereby reducing mitochondrial damage and increase mitochondrial function.

Abstract
Objective: To examine the overall status of the Jiangsu Province Coronary Artery Bypass Grafting Registry database. Methods: The patients date of Jiangsu Province Coronary Artery Bypass Grafting Registry database from October 2017 to December 2019 was collected retrospectively.Risk factors, history, cardiac function (New York Heart Association class), extent of coronary artery lesion, European system for cardiac operative risk evaluation Ⅱ (EuroSCORE Ⅱ), cardiopulmonary bypss, arterial grafts, the numbers and flow of grafts and postoperative major adverse cardiac and cerebrovascular event(MACCE) information were analyzed. The clinical data of patients underwent on-pump CABG(ONCABG) or off-pump CABG (OPCAB) were compared by t test or χ(2) test. Results: Up till December 2019, the database enrolled 7 138 patients, in which 4 661 patients receiving primary isolated CABG. There were 3 486 males and 1 175 females with the age of (64.6±8.1) years (range:31 to 87 years). There were coronary left main disease in 960 patients, triple vessel disease in 3 934 patients, both left main and triple vessel disease in 837 patients, ejection fraction>50% in 3 841 patients, cardiac function class Ⅲ to Ⅳ in 1 664 patients. EuroSCORE Ⅱ was (2.3±0.7)% (range: 0.5% to 35.8%). There were 2 731 patients (58.59%) underwent ONCABG and 1 930 patients (41.41%) underwent OPCAB. There were 4 144 patients (88.91%) for whom the left internal thoracic artery was harvested. Seven centers (2 centers routinely) used left radial artery, 5 centers (3 centers routinely) used the transit time flow meter. The graft was 3.4±0.7 (range:1 to 7), the aortic crossclamp time was (65.0±20.4) minutes (range: 21 to 196 minutes), the cardiopulmonary bypass time was (90.0±24.2) minutes (range: 33 to 227 minutes). In-hospital death ocurred in 84 patients(1.80%), while re-operation in 93 patients (2.00%), myocardial infarction in 71 patients (1.52%), cerebral infarction in 33 patients (0.71%) and dialysis in 56 patients (1.20%). There were 2 936 patients prescribed with secondary prevention drugs(62.99%).Comparing with OPCAB group, ONCABG group had younger age, more female, more diabetes mellitus, more history of myocardial infarction and percutaneous transluminal coronary angioplasty, poorer cardiac function and coronary lesions, higher EuroSCORE Ⅱ, preoperatively (all P<0.05), and was associated with higher MACCE (135/2 731 vs. 71/1 930, χ(2)=4.280, P=0.039), and of more grafts, transfusion and intra-aortic balloon counterpulsation application (all P<0.05). Conclusions: Jiangsu Province Coronary Artery Bypass Grafting Registry database is generally in good operation, and some parameters still need to be improved. Comparing with OPCAB group, ONCABG has more severe preoperative general conditions, while the outcomes is acceptable.

Abstract
Objective:To explore effect of mobile platform in improving compliance and efficacy of subcutaneous immunotherapy(SCIT) in children with allergic rhinitis(AR). Method:From January to June 2018, 86 children diagnosed with AR and receiving SCIT were selected as research objects. According to the random sequence generated by the computer, the research objects were randomly assigned to the experimental group and the control group, with 43 cases in each group. The control group received conventional SCIT management, while the experimental group received mobile platform SCIT management relying on smart phones and computers. The SCIT shedding rate at the initial stage and the time taken to reach the maintenance period were compared between the two groups, as well as the visual simulation scale of rhinitis symptoms, four-point score and rhinoconjunctivia-related quality of life scores before and at the 6th month after the intervention. Result:There was no statistically significant difference in the initial SCIT shedding rate between the two groups(P>0.05), and the average duration of the maintenance period of the experimental group was shorter than that of the control group, with statistically significant difference(P<0.05). At the 6th month after intervention, there was no statistically significant difference in the scores of rhinitis symptoms by the four-point method between the two groups(P>0.05), and there were statistically significant differences in the visual simulation scale of rhinitis symptoms and the scores of children's rhinoconjunctivia-related quality of life(P<0.05). Conclusion:This study confirmed that the application of a mobile platform is of great significance for improving compliance and the treatment effects of SCIT in children with AR.

Abstract
BACKGROUND Loss of graft function after liver transplantation (LT) inevitably requires liver retransplant. Retransplantation of the liver (ReLT) remains controversial because of inferior outcomes compared with the primary orthotopic LT (OLT). Meanwhile, if accompanied by vascular complications such as arterial and portal vein (PV) stenosis or thrombosis, it will increase difficulties of surgery. We hereby introduce our center's experience in ReLT through a complicated case of ReLT.
CASE SUMMARY We report a patient who suffered from hepatitis B-associated cirrhosis and underwent LT in December 2012. Early postoperative recovery was uneventful. Four months after LT, the patient’s bilirubin increased significantly and he was diagnosed with an ischemic-type biliary lesion caused by hepatic artery occlusion. The patient underwent percutaneous transhepatic cholangial drainage and repeatedly replaced intrahepatic biliary drainage tube regularly for 5 years. The patient developed progressive deterioration of liver function and underwent liver re-transplant in January 2019. The operation was performed in a classic OLT manner without venous bypass. Both the hepatic artery and PV were occluded and could not be used for anastomosis. The donor PV was anastomosed with the recipient’s left renal vein. The donor hepatic artery was connected to the recipient’s abdominal aorta. The bile duct reconstruction was performed in an end-to-end manner. The postoperative process was very uneventful and the patient was discharged 1 mo after retransplantation.
CONCLUSION With the development of surgical techniques, portal thrombosis and arterial occlusion are no longer contraindications for ReLT.

Abstract
In this study, we determined whether multilineage‐differentiating stress‐enduring (Muse) cells exist in rat bone marrow and elucidated their effects on protection against the injury of intestinal epithelial cells associated with inflammation. Rat Muse cells were separated from bone marrow mesenchymal stem cells (BMMSCs) by trypsin‐incubation stress. The group of cells maintained the characteristics of BMMSCs; however, there were high positive expression levels of stage‐specific embryonic antigen‐3 (SSEA‐3; 75.6 ± 2.8%) and stage‐specific embryonic antigen‐1 (SSEA‐1; 74.8 ± 3.1%), as well as specific antigens including Nanog, POU class 5 homeobox 1 (OCT 3/4), and SRY‐box 2 (SOX 2). After inducing differentiation, α‐fetoprotein (endodermal), α‐smooth muscle actin and neurofilament medium polypeptide (ectodermal) were positive in Muse cells. Injuries of intestinal epithelial crypt cell‐6 (IEC‐6) and colorectal adenocarcinoma 2 (Caco‐2) cells as models were induced by tumor necrosis factor‐α stimulation in vitro. Muse cells exhibited significant protective effects on the proliferation and intestinal barrier structure, the underlying mechanisms of which were related to reduced levels of interleukin‐6 (IL‐6) and interferon‐γ (IFN‐γ), and the restoration of transforming growth factor‐β (TGF‐β) and IL‐10 in the inflammation microenvironment. In summary, there were minimal levels of pluripotent stem cells in rat bone marrow, which exhibit similar properties to human Muse cells. Rat Muse cells could provide protection against damage to intestinal epithelial cells depending on their anti‐inflammatory and immune regulatory functionality. Their functional impact was more obvious than that of BMMSCs.

Abstract
BACKGROUND Highly upregulated in liver cancer (HULC) is a long non-coding RNA (lncRNA) which has recently been identified as a key regulator in hepatocellular carcinoma (HCC) progression. However, its role in the secretion of exosomes from HCC cells remains unknown.
AIM To explore the mechanism by which HULC promotes the secretion of exosomes from HCC cells.
METHODS Serum and liver tissue samples were collected from 30 patients with HCC who had not received chemotherapy, radiotherapy, or immunotherapy before surgery. HULC expression in serum exosomes and liver cancer tissues of patients was measured, and compared with the data obtained from healthy controls and tumor adjacent tissues. The effect of HULC upregulation in HCC cell lines and the relationship between HULC and other RNAs were studied using qPCR and dual-luciferase reporter assays. Nanoparticle tracking analysis was performed to detect the quantity of exosomes.
RESULTS HULC expression in serum exosomes of patients with HCC was higher than that in serum exosomes of healthy controls, and HULC levels were higher in liver cancer tissues than in tumor adjacent tissues. The expression of HULC in serum exosomes and liver cancer tissues correlated with the tumor-node-metastasis (TNM) classification, and HULC expression in tissues correlated with that in serum exosomes. Upregulation of HULC promoted HCC cell growth and invasion and repressed apoptosis. Notably, it also facilitated the secretion of exosomes from HCC cells. Moreover, qPCR assays showed that HULC repressed microRNA-372-3p (miR-372-3p) expression. We also identified Rab11a as a downstream target of miR-372-3p. Dual-luciferase reporter assays suggested that miR-372-3p could directly bind both HULC and Rab11a.
CONCLUSION Our findings illustrate the importance of the HULC/miR-372-3p/Rab11a axis in HCC and provide new insights into the molecular mechanism regulating the secretion of exosomes from HCC cells.

Abstract
Objective: To analyze the change trend of HIV genetic subtypes and compare the first CD(4)(+)T cell counts of newly diagnosed HIV infected patients in Liuzhou from 1998 to 2012, and provide a reference for AIDS prevention and control. Methods: Newly diagnosed HIV-infected patients from 1998 to 2012 in Liuzhou were selected through national HIV/ADIS comprehensive response information management system. Their plasma samples were used for RNA gene extraction, amplification, sequencing and genotyping. Coharan-Armitage trend test was used to analyze the ratio trend of genetic subtypes and phylogenetic clusters of HIV and Wilcoxon Rank Sum Test was used to compare the first CD(4)(+)T cell counts (CD(4)) of the different subtype HIV infected patients. Results: A total of 1 877 newly diagnosed HIV infected patients were included in the study. From 1998 to 2012, the proportions of CRF01_AE and CRF01_AE (Cluster 1) increased from 78.4% (76/97) to 91.5% (1 441/1 574), from 63.9% (62/97) to 74.0% (1 164/1 574), and the proportion of CRF07_BC decreased from 17.5% (17/97) to 4.6% (72/1 574), respectively (Z=4.632, P<0.001; Z=2.455, P=0.014; Z=-5.943, P<0.001). The median and interquartile range of the first CD(4) of the patients infected with subtype CRF01_AE (Cluster 1), CRF01_AE (Cluster 2), CRF07_BC and CRF08_BC were 230 (83-375), 215 (48-351), 365 (254-503) and 334 (206-479) cell/μl, respectively. The first CD(4) levels of the patients infected with subtype CRF01_AE (Cluster 1) or CRF01_AE (Cluster 2) were significantly lower than those of CRF07_BC (Z=-4.795, P<0.001; Z=-4.238, P<0.001). Conclusion: The genetic subtypes of HIV were mainly CRF01_AE in newly diagnosed HIV-infected patients and this subtype proportion was in increase and the first CD(4) levels of the patients were low in Liuzhou during 1998 to 2012.

Abstract
BACKGROUND Mizoribine (MZR) was effective and safe for living Chinese donor kidney transplantation (LDKT) on tacrolimus-based treatment 1 year after transplantation. We investigated whether MZR was effective and safe for LDKT on tacrolimus-based treatment with long follow-up periods. METHODS We compared 22 LDKT recipients who were administered MZR, tacrolimus, and corticosteroids with a control group (n = 20) treated with mycophenolate mofetil (MMF), tacrolimus, and corticosteroids. Primary efficacy endpoints were 3-year patient survival, 3-year graft survival, and acute rejection (AR) rate within 3 years after transplantation. RESULTS The 3-year patient and graft survival rates for the MZR and MMF groups were 100%. The AR rate after transplantation was 18.2% for the MZR group and 10.0% for the MMF group; the difference was not significant (P = .665). There was no significant difference in serum creatinine levels, glomerular filtration rates (eGFR), serum urate levels, blood urea nitrogen, and cystatin C levels 12, 24, and 36 months after transplantation. No significant differences in the CD3, CD4, CD8, CD4/CD8, and CD45 were observed between the 2 groups 12, 24, and 36 months after transplantation. There were no significant differences in adverse events among the MZR or the MMF group, whereas the prevalence of gastrointestinal symptoms were significantly lower in the MZR treatment group (P = .003), especially acid reflux (P = .007). Compared with the MMF group, the MZR group should lighten the burden on patients. CONCLUSION MZR with tacrolimus and corticosteroids provides satisfactory immunosuppression and higher safety for Chinese LDKT over a 3-year follow-up.

Abstract
BACKGROUND Although mizoribine (MZR) is used as an immunosuppressant after renal transplantation, the occurrence of hyperuricemia has been reported. The onset of hyperuricemia is often observed within the first several months after surgery. Since MZR is a renal excretion-type drug excreted as an unchanged drug from the kidneys, MZR blood concentrations may rise due to the influence of renal function. We investigated whether the onset of hyperuricemia after MZR administration was associated with the direct effect of a change in renal function. METHODS Serum uric acid (serum UA), serum creatinine (sCr), serum β2-microglobulin (serum β2-MG), and serum cystatin C (serum Cys-C) were measured for about 3 months in 22 subjects. Correlation coefficients were calculated using the change rates of serum UA and sCr (Δ serum UA, Δ sCr), serum UA and serum β2-MG (Δ serum UA, Δ serum β2-MG), and serum UA and serum Cys-C (Δ serum UA, Δ serum Cys-C) at the onset of hyperuricemia. RESULTS The correlation coefficients between Δ serum UA and Δ sCr, Δ serum UA and Δ serum β2-MG, and Δ serum UA and Δ serum Cys-C were 0.723 (P < .001), 0.863 (P < .001) and 0.548 (P < .001), respectively. Further, serum UA and sCr level reached their highest peak on the same day after MZR administration, and the behavior was mostly consistent. CONCLUSION It was suggested that hyperuricemia occurred about 3 months after MZR administration due mainly to temporary changes in kidney function.

Abstract
Objective: To investigate the relationship between psoas muscle index (PMI) and early postoperative survival rate and the incidence of complications after liver transplantation in adults. Methods: The clinical data of 225 patients (male, n=184; female, n=41) underwent liver transplantation at the Organ Transplantation Department of First Central Clinic Institute of Tianjin Medical University from January 2014 to December 2016 were analyzed, retrospectively.Original disease: hepatitis B liver cirrhosis(44 cases), hepatitis C cirrhosis(10 cases), autoimmune liver cirrhosis(29 cases), other benign liver diseases(24 cases), liver cirrhosis with liver cancer(116 cases), hilar cholangiocarcinoma(1 case) and hepatic vascular sarcoma(1 case). The area of bilateral psoas muscle on the lower edge level of the third lumbar vertebral body was measured through preoperative CT image.The PMI was calculated using this formula: bilateral psoas muscle area (mm(2))/the square of the body height (m(2)). According to the receiver operating characteristic curve and cut-off values, the male and female patients were divided into low PMI group and high PMI group respectively.The χ(2) test, Fisher exact test and t-test was used to compare the differences in perioperative data, survival rate and postoperative complications between the two groups, respectively. Results: There were 44 patients in the low PMI group, and 181 patients in the high PMI group. ICU time was longer (82.5(62.0-128.0) hours vs.69.1(56.0-104.0) hours; P=0.006) and preoperative blood urea nitrogen level (5.86(4.35-15.52) mmol/L vs. 4.94(4.05-7.06) mmol/L; P=0.012) was higher in the low PMI group than those in the high PMI group. Incidence rates of grade 5 complication (18.2%) and grade 4a complication (18.2%) were higher in the low PMI group, and 120-day cumulative survival rate was lower than that in high PMI group(81.8% vs. 95.6%, P=0.001). On the other hand, there were no significant differences in preoperative white blood cell count level, serum creatinine level, operative time, anhepatic period time, intraoperative blood loss, and incidence of postoperative grade 3 complications between the two groups(all P>0.05). Conclusions: There is a significant correlation between PMI and early postoperative survival rate and incidence of complications.Patients with lower PMI has poor prognosis after liver transplantation.

Abstract
Objective: To understand the characteristics of HIV infected persons without long term disease progress [also known as long term non-progressors (LTNPs)], and related factors in Guangxi Zhuang Autonomous Region (Guangxi). Methods: Data of persons living with HIV and receiving no antiretroviral therapy in Guangxi by the end of 2016 were collected from the national HIV/AIDS comprehensive control and prevention information system of China. Results: By the end of 2016, there were 313 LTNPs in Guangxi, accounting for 2.3% of those being reported for more than 10 years, 5.4% of those being reported for more than 10 years and surviving, and 26.6% of those being reported for more than 10 years, surviving and receiving no antiretroviral therapy. Among the LTNPs, 87.2%(273) were men, 94.9% (297) were aged ≤ 40 years, 32.3% (101) were farmers, 55.6% (174) were single, divorced or widowed, 69.3% (217) were of Han ethnic group, 68.1% (213) were injecting drug users, and 52.1% (163) were from custody facilities. Multiple logistic regression analysis indicated that factors associated with delayed disease progression included age ≤40 years (compared with age >40 years, aOR=1.55, 95%CI: 1.31-3.12) and injection drug use (compared with sexual transmission, aOR=1.23, 95%CI: 1.10-1.74). Conclusions: A number of LTNPs existed in HIV-infected individuals in Guangxi. Further research are needed to identify the related factors, and it is necessary to conduct large sample size studies on host immunology, genetics and the virology of HIV to explore the related mechanism.

Abstract
Background Normothermic machine perfusion (NMP) preservation is superior to cold preservation during reduced-size liver transplantation (RSLT) in pigs. However, the mechanism of this protective effect has not been explained. We aimed to compare the effects of NMP preservation with that of cold preservation (CS) in protecting against ischemia-reperfusion injury (IRI) during RSLT in pigs. Material/Methods Twenty-four healthy Bama miniature pigs were randomized into 2 groups: 1) the NMP group in which donor livers harvested without warm ischemia time and cardiac activity were connected to the NMP system to reduce liver size under normothermic conditions, and 2) the CS group in which donor livers harvested without warm ischemia time and cardiac activity were perfused using the University of Wisconsin (UW) solution and then preserved in the 0–4°C UW solution to reduce liver size under cold conditions. Livers were then transplanted without veno-venous bypass. Amounts of bile secretion for the NMP groups were recorded hourly. The serological indices were measured. Expressions of cytochrome C, caspase 3, and NF-κB p65 in liver tissue were observed. Results The levels of bile secretions were gradually diminished from 16.50±2.66 mL/h before splitting to 6.35±1.24 mL/h after splitting. With the exception of TNF-α on postoperative day 2, overall, levels of TNF-α, IL-1, IL-6, and MDA were significantly lower in the NMP group versus CS group for all 5 days postoperatively. Finally, cytochrome C, caspase 3, and NF-κB p65 expressions were all significantly suppressed in the NMP group as compared with the CS group. Conclusions MP preservation is superior to cold preservation in protecting against liver IRI during RSLT in pigs.

Abstract
BACKGROUND Acne vulgaris is a common chronic skin disease. Inflammation is an important pathogenetic mechanism of acne, and NLRP3 polymorphisms have been reported to be involved in the mediation and occurrence of the inflammation. However, only a few studies on NLRP3 and acne have been reported, and the mechanism remains unclear. AIM To investigate two SNPs in the NLRP3 gene in patients with acne vulgaris (AV) and healthy controls (HCs) in a Chinese population. METHODS A case-control study was performed with 428 patients with AV and 384 (HCs). The SNPs rs10754558 and rs4612666 of the NLRP3 gene were genotyped using PCR with sequence-specific primers. A dual luciferase reporter assay was performed to determine whether the SNP rs10754558 might be responsible for the altered NLRP3 gene expression in AV by disrupting the interaction between micro-RNA (miR)-4273 and NLRP3 mRNA. Additionally, the mRNA level of NLRP3 was measured by PCR in the two groups. RESULTS The frequencies of the G allele of rs10754558 were 0.54 in patients and 0.49 in HCs (P < 0.05). No significant difference was observed for SNP rs4612666. Dual luciferase reporter assay revealed that luciferase activity was downregulated by about 40% when the G allele of rs10754558 coexisted with miRNA-4273, indicating that the G allele might interfere with miR-4273 function and alter NLRP3 expression. The level of NLRP3 mRNA in patients with AV was significantly higher than that in HCs. CONCLUSIONS Our study suggests that the NLRP3 SNP rs10754558 is associated with the incidence of AV. The G allele might be a genetic risk factor for AV in the Chinese population.

Abstract
Objective: To understand the dynamic variation of BMI and influencing factors among HIV/AIDS patients receiving highly active anti-retroviral therapy (HAART) in Liuzhou, Guangxi Zhuang Autonomous Region (Guangxi). Methods: HIV/AIDS patients receiving HAART for the first time since 1 January 2013 were selected. Data on BMI was analyzed among patients receiving HAART at baseline,6 months and 12 months after treatment. By using the general linear model repeated measures of analysis of variance, BMI dynamic variations and influencing factors were described and analyzed. Results: The average BMI of 2 871 patients at baseline, 6th months and 12th months appeared as (20.65±3.32), (20.87±3.22) and (21.18±3.20), respectively, with differences all statistically significant (F=18.86, P<0.001). BMI were increasing over time with treatments (F=37.25, P<0.001). Main influencing factors were noticed as: age, sex, marital status, baseline data of CD(4)(+)T cells and the WHO classification on clinical stages. Conclusions: Higher proportion of BMI malnutrition counts was seen among patients before receiving HAART in Liuzhou. BMI of the patients that were on HAART seemed being influenced by many factors. It is necessary to select appropriate treatment protocols on different patients so as to improve the nutritional status of the patients.

Abstract
Objective: To explore the significance of multi-parameter semiquantitative Alberta Stroke Program Early CT Score (ASPECTS) in detecting core infarction in acute ischemic stroke (AIS) patients. Methods: Twenty-one consecutive AIS patients from Beijing Hospital were retrospectively reviewed in this study from August 2016 to August 2017. All the patients presented within 6 hours since symptom onset.All the patients underwent one-stop dynamic whole brain 4D CTA-CTP scan before treatments (intravenous thrombolysis, mechanical thrombectomy, or other endovascular recanalization). MRI scan was performed in all patients 3 to 7 days after initial administration. Multi-parameter ASPECTS was calculated on the affected hemisphere regarding noncontrast CT (NCCT) map, cerebral blood flow (CBF) map, cerebral blood volume (CBV) map, mean transit time (MTT) map and MRI-DWI map by subtracting 1 point from 10 for any abnormalities visually detected. The evaluative consistency and diagnostic efficiency were analyzed by Pearson's χ(2) test, kappa identity test, and Kendall's coefficient of concordance using IBM SPSS statistics 22.0 software. Results: Compared with DWI-ASPECTS or follow-up NCCT-ASPECTS, CBV-ASPECTS had the best performance on both the kappa identity test (kappa coefficient κ=0.74)and Kendall's coefficient of concordance (τ=0.70). All the values of sensitivity (77.8%), specificity (95.5%), positive likelihood ratio (17.27) and AUC(0.87)were the highest in CBV-ASPECTS, followed by dMTT-ASPECTS. Meanwhile, the misdiagnosis rate (4.5%), missed diagnosis rate (22.2%) and negative likelihood ratio were the lowest in CBV-ASPECTS, followed by dMTT-ASPECTS. dMTT-ASPECTS had the same specificity(95.5%) as CBV-ASPECTS did and it could reveal the infarction in the areas where CBV map showed normal. NCCT-ASPECTS had the lowest sensitivity (64.7%) and highest missed diagnosis rate (35.3%). The misdiagnosis rate of CBF-ASPECTS was the highest (25.2%) and AUC was the lowest (0.76). Conclusions: Multi-parameter semiquantitative ASPECTS may predict the infarction accurately in AIS patients. Compared with the single parameter of NCCT-ASPECTS, this new method may have better detectability and diagnostic performance.

Abstract
The prognostic values of IRF-1 and Ki-67 for liver transplantation (LT) of hepatocellular carcinoma (HCC) were investigated, as well as the mechanisms of IRF-1 in tumor suppression. Adult orthotropic liver transplantation cases (N = 127) were involved in the analysis. A significant decreased recurrence free survival (RFS) was found in the Ki-67 positive groups. Ki-67, tumor microemboli, the Milan and UCSF criteria were found to be independent risk factors for RFS. In LT for HCC beyond the Milan criteria, a significant decrease in RFS was found in the IRF-1 negative groups. In SK-Hep1 cells, an increase in apoptosis and decrease in autophagy were observed after IFN-γ stimulation, which was accompanied with increasing IRF-1 levels. When IRF-1 siRNA or a caspase inhibitor were used, reductions in LC3-II were diminished or disappeared after IFN-γ stimulation, suggesting that IFN-γ inhibited autophagy via IRF-1 expression and caspase activation. However, after IRF-1 siRNA was introduced, a reduction in LC3-II was found. Thus basic expression of IRF-1 was also necessary for autophagy. IRF-1 may be used as a potential target for HCC treatment based on its capacity to affect apoptosis and autophagy. Ki-67 shows great promise for the prediction of HCC recurrence in LT and can be used as an aid in the selection of LT candidates.

Abstract
Highly upregulated in liver cancer (HULC), a lncRNA that is considered a key molecule in human liver cancer, has recently been revealed to be involved in hepatocellular carcinoma (HCC) development and progression [1, 2]. It has been reported that HULC can promote tumor invasion and metastasis of HCC, but its function and mechanism of action in HCC have not been elucidated. In this study, we found that HULC was aberrantly up-regulated in HCC tissues and associated with TNM stage, intrahepatic metastases, HCC recurrence, and postoperative survival. HULC depletion inhibited the growth and metastasis of HCC cell lines in vitro and in vivo. Moreover, HULC contributes to ZEB1-induced epithelial-mesenchymal transition (EMT), a requirement for tumor invasion and metastasis that plays a key role in cancer progression. This effect of ZEB1 was inhibited by HULC siRNA. We conclude that the HULC functioned as a competing endogenous RNA (ceRNA) to mediate EMT via up-regulating ZEB1. In this way, it sequesters the miR-200a-3p signaling pathway to facilitate HCC metastasis. HULC comes into play as an oncogene in HCC, acting mechanistically by inducing HCC cells to activate EMT. Such an effect promotes tumor progression and metastasis through the miR-200a-3p/ZEB1 signaling pathway. The identification of this novel pathway that links high expression levels of HULC with EMT in HCC cells may serve as the foundation for the development of novel anti-tumor therapeutics.

Abstract
Simultaneous liver, pancreas-duodenum, and kidney transplantation has been rarely reported in the literature. Here we present a new and more efficient en bloc technique that combines classic orthotopic liver and pancreas-duodenum transplantation and heterotopic kidney transplantation for a male patient aged 44 years who had hepatitis B related cirrhosis, renal failure, and insulin dependent diabetes mellitus (IDDM). A quadruple immunosuppressive regimen including induction with basiliximab and maintenance therapy with tacrolimus, mycophenolate mofetil, and steroids was used in the early stage post-transplant. Postoperative recovery was uneventful and the patient was discharged on the 15th postoperative day with normal liver and kidney function. The insulin treatment was completely withdrawn 3 wk after operation, and the blood glucose level remained normal. The case findings support that abdominal organ cluster and kidney transplantation is an effective method for the treatment of end-stage liver disease combined with uremia and IDDM.

Abstract
Objective: To understand HIV-1 subtype characteristics and transmission clusters in elderly male clients and female sex workers (FSWs) of low-cost commercial sex venues in Guangxi Zhuang Autonomous Region, China. Methods: A cross sectional survey was conducted in FSWs and elderly male clients (≥50 years) of low-cost commercial sex venues in 4 cities and 9 counties in Guangxi Zhuang Autonomous Region by convenient sampling in 2012. The blood sample was collected from each case for HIV-1 antibody detection. The pol gene fragments were amplified and sequenced from viral RNA template extracted from plasma samples. The phylogenetic tree was constructed and the subtypes were identified. Results: A total of 4 048 elderly male clients and 784 FSWs were surveyed, and 116 HIV-1 infections were detected, the positive rate was 2.5% (103/4 048) in the clients and 1.7% (13/784) in FSWs. The gene amplification and sequencing of HIV-1 detected in 84 blood samples indicated that 53 pol gene sequences were successfully determined (48 blood samples from elderly male clients and 5 blood samples from FSWs). Among 53 pol sequences, 48(90.6% ), 4(7.5% ), and 1(1.9% ) sequences were identified as CRF01_AE, CRF08_BC, and CRF07_BC, respectively. Two transmission clusters were identified among CRF01_AE, including 4 sub-clusters. One transmission cluster was identified among CRF08_BC. The transmission cluster or sub-cluster were from the infected individuals at same low-cost commercial sex venue, or different low-cost commercial sex venues in the same town, or same place, or adjacent villages and towns. Conclusions: CRF01_AE was the predominant HIV-1 subtype among elderly male clients and FSWs of low-cost commercial sex venues in Guangxi Zhuang Autonomous Region, circulating in same venue or adjacent villages and towns. The HIV-1 positive male clients and FSWs might play an important role in the spread of the strains.

Abstract
BACKGROUND Studies have shown that normothermic machine perfusion (NMP) exerts a significant protective role for donations after cardiac death (DCD) livers and verified the effects of NMP in preservation, repair, and preoperative assessment of human donor livers. The objective of this study was to verify the effectiveness and stability of NMP system by splitting pig livers in perfusion preservation. MATERIAL AND METHODS Four healthy Ba-Ma miniature pigs were used. The livers were harvested, and then connected to the NMP system to split the livers. The indexes during the splitting were recorded, the serological indices were measured, and routine pathological examination of liver tissue were observed. RESULTS With splitting, the portal vein pressure and the hepatic artery pressure were not significantly changed. The flow in the portal vein and hepatic artery reduced respectively from 455±107.55 mmHg, 180.75±59.46 mmHg before splitting to 392.5±125.27 mmHg and 126.25±6.99 mmHg after splitting. The liver preservation temperature was controlled to 38.83±0.24 to 38.93±0.43°C during splitting. At the beginning of perfusion preservation, the alanine aminotransferase(ALT), lactate dehydrogenase(LDH), and alkaline phosphatase (ALP) were lower than the baseline level; ALT and LDH gradually increased with splitting, whereas ALP was maintained in a lower level in the splitting. At the beginning of perfusion preservation, aspartate aminotransferase(AST) was comparable with the baseline value, and it was gradually increased with splitting. The cell structure in the liver before NMP preservation and after splitting did not show significant changes. CONCLUSIONS The NMP device developed in this study can be used for donor liver preservation and splitting, without causing significant liver damage.

Abstract
Objective: To understand the HIV transmission and associated factors in newly reported HIV infected couples before diagnosis. Methods: The information about newly reported HIV infected couples in Yunnan, Guangxi, Sichuan, Henan and Xinjiang provinces (autonomous region) were collected from National HIV/AIDS Information System from 2011 to 2014. The infection order of the sero-concordant couples were determined. Logistic regression model was used to analyze the HIV transmission between couples and identify the associated factors. Cochran-Armitage trend analysis was conducted to understand the annual sero-concordant couple proportion. Results: A total of 48 931 HIV cases in couples were included in this study, among whom 12 051(24.6%) were sero-concordant couples, indicating HIV transmissions occurred between them. Multivariate logistic regression analysis showed that those who were females (OR=1.98, 95%CI: 1.89-2.08), aged >45 years (45-59 yrs: OR=1.32, 95% CI: 1.23-1.42; >60 yrs: OR=1.72, 95% CI: 1.58-1.86), had educational level of middle school education or below (illiteracy and primary school: OR=1.33, 95%CI: 1.23-1.44; middle school: OR=1.19, 95% CI: 1.10-1.28), were farmers or migrate workers (OR=1.23, 95% CI: 1.17-1.30), were infected through injecting drug use or heterosexual intercourse (injecting drug use: OR=1.33, 95% CI: 1.03-1.72; heterosexual intercourse: OR=3.65, 95% CI: 2.89-4.61), had CD4+T cells of <500 cells/μl (<200 cells/μl: OR=5.05, 95%CI: 4.62-5.52; 200-349 cells/μl: OR=3.58, 95%CI: 3.26-3.93; 350-500 cells/μl: OR=2.14, 95%CI: 1.94-2.36), reported unprotected sexual behaviors (OR=1.56, 95% CI: 1.49-1.64), were more likely to infect their couples before diagnosis. The HIV transmission proportion between couples before diagnosis decreased significantly from 28.9% (2 631/9 102) in 2011 to 25.5% (3 009/11 787) in 2014 among those infected through heterosexual intercourse. Conclusion: The proportion of HIV transmission between couples before diagnosis varied among different populations. Behavior intervention and early HIV test promoting are needed to prevent HIV transmission between couples before diagnosis in populations at high risk for HIV infection. HIV infection cases should be included in the HIV care system after diagnosis as early as possible.

Abstract
AIM To investigate whether bone marrow mesenchymal stem cells (BMMSCs) modified with the HO-1 and CXCR3 genes can augment the inhibitory effect of BMMSCs on small bowel transplant rejection.
METHODS Lewis rat BMMSCs were cultured in vitro. Third-passage BMMSCs were transduced with the CXCR3/HO-1 genes or the HO-1 gene alone. The rats were divided into six groups and rats in the experimental group were pretreated with BMMSCs 7 d prior to small bowel transplant. Six time points (instant, 1 d, 3 d, 7 d, 10 d, and 14 d) (n = 6) were chosen for each group. Hematoxylin-eosin staining was used to observe pathologic rejection, while immunohistochemistry and Western blot were used to detect protein expression. Flow cytometry was used to detect T lymphocytes and enzyme linked immunosorbent assay was used to detect cytokines.
RESULTS The median survival time of BMMSCs from the CXCR3/HO-1 modified group (53 d) was significantly longer than that of the HO-1 modified BMMSCs group (39 d), the BMMSCs group (26 d), and the NS group (control group) (16 d) (P < 0.05). Compared with BMMSCs from the HO-1 modified BMMSCs, BMMSCs, and NS groups, rejection of the small bowel in the CXCR3/HO-1 modified group was significantly reduced, while the weight of transplant recipients was also significantly decreased (P < 0.05). Furthermore, IL-2, IL-6, IL-17, IFN-γ, and TNF-α levels were significantly decreased and the levels of IL-10 and TGF-β were significantly increased (P < 0.05).
CONCLUSION BMMSCs modified with the CXCR3 and HO-1 genes can abrogate the rejection of transplanted small bowel more effectively and significantly increase the survival time of rats that receive a small bowel transplant.

Abstract
AIM To investigate the effects of heme oxygenase-1 (HO-1)-modified bone marrow mesenchymal stem cells (BMMSCs) on the microcirculation and energy metabolism of hepatic sinusoids following reduced-size liver transplantation (RLT) in a rat model.
METHODS BMMSCs were isolated and cultured in vitro using an adherent method, and then transduced with HO-1-bearing recombinant adenovirus to construct HO-1/BMMSCs. A rat acute rejection model following 50% RLT was established using a two-cuff technique. Recipients were divided into three groups based on the treatment received: normal saline (NS), BMMSCs and HO-1/BMMSCs. Liver function was examined at six time points. The levels of endothelin-1 (ET-1), endothelial nitric-oxide synthase (eNOS), inducible nitric-oxide synthase (iNOS), nitric oxide (NO), and hyaluronic acid (HA) were detected using an enzyme-linked immunosorbent assay. The portal vein pressure (PVP) was detected by Power Lab ML880. The expressions of ET-1, iNOS, eNOS, and von Willebrand factor (vWF) protein in the transplanted liver were detected using immunohistochemistry and Western blotting. ATPase in the transplanted liver was detected by chemical colorimetry, and the ultrastructural changes were observed under a transmission electron microscope.
RESULTS HO-1/BMMSCs could alleviate the pathological changes and rejection activity index of the transplanted liver, and improve the liver function of rats following 50% RLT, with statistically significant differences compared with those of the NS group and BMMSCs group (P < 0.05). In term of the microcirculation of hepatic sinusoids: The PVP on POD7 decreased significantly in the HO-1/BMMSCs and BMMSCs groups compared with that of the NS group (P < 0.01); HO-1/BMMSCs could inhibit the expressions of ET-1 and iNOS, increase the expressions of eNOS and inhibit amounts of NO production, and maintain the equilibrium of ET-1/NO (P < 0.05); and HO-1/BMMSCs increased the expression of vWF in hepatic sinusoidal endothelial cells (SECs), and promoted the degradation of HA, compared with those of the NS group and BMMSCs group (P < 0.05). In term of the energy metabolism of the transplanted liver, HO-1/BMMSCs repaired the damaged mitochondria, and improved the activity of mitochondrial aspartate aminotransferase (ASTm) and ATPase, compared with the other two groups (P <0.05).
CONCLUSION HO-1/BMMSCs can improve the microcirculation of hepatic sinusoids significantly, and recover the energy metabolism of damaged hepatocytes in rats following RLT, thus protecting the transplanted liver.

Abstract
The aim of the present study was to explore the effects of co‑culturing bone marrow‑derived mesenchymal stem cells (BM-MSCs) cultured with hepatitis B virus (HBV)‑infected lymphocytes in vitro. BM‑MSCs and lymphocytes from Brown Norway rats were obtained from the bone marrow and spleen, respectively. Rats were divided into the following five experimental groups: Group 1, splenic lymphocytes (SLCs); group 2, HepG2.2.15 cells; group 3, BM‑MSCs + HepG2.2.15 cells; group 4, SLCs + HepG2.2.15 cells; and group 5, SLCs + BM‑MSCs + HepG2.2.15 cells. The viability of lymphocytes and HepG2.2.15 cells was assessed using the MTT assay at 24, 48 and 72 h, respectively. Levels of supernatant HBV DNA and intracellular HBV covalently closed circular DNA (cccDNA) were measured using quantitative polymerase chain reaction. Supernatant cytokine levels were measured by enzyme‑linked immunosorbent assay (ELISA). T cell subsets were quantified by flow cytometry using fluorescence‑labeled antibodies. In addition, the HBV genome sequence was analyzed by direct gene sequencing. Levels of HBV DNA and cccDNA in group 5 were lower when compared with those in group 3 or group 4, with a significant difference observed at 48 h. The secretion of interferon‑γ was negatively correlated with the level of HBV DNA, whereas secretion of interleukin (IL)‑10 and IL‑22 were positively correlated with the level of HBV DNA. Flow cytometry demonstrated that the percentage of CD3+CD8+ T cells was positively correlated with the levels of HBV DNA, and the CD3+CD4+/CD3+CD8+ ratio was negatively correlated with the level of HBV DNA. Almost no mutations in the HBV DNA sequence were detected in HepG2.2.15 cells co‑cultured with BM‑MSCs, SLCs, or in the two types of cells combined. BM‑MSCs inhibited the expression of HBV DNA and enhanced the clearance of HBV, which may have been mediated by the regulation of the Tc1/Tc2 cell balance and the mode of cytokine secretion to modulate cytokine expression.

Abstract
OBJECTIVE To analyse and explore the indications and efficacy of liver transplantation for benign liver tumor. METHODS From Jan.2001 to Dec.2014, 6 patients, incluing 3 males and 3 females, with benign liver tumor underwent liver transplantation in our department.There were 2 cases of hepatic epithelioid hemangioendothelioma, 1 case of hepatic cavernous hemangioma, 1 case of liver mesenchymal hamartoma, 1 case of hilar bile duct mucinous cystadenoma, and 1 case of hepatic adenoma. The data of surgical procedure, perioperative complications, postoperative management, and the outcome of follow-up were analyzed. RESULTS Six orthotopic liver transplantation from one living donor and five cadaveric donors were performed. One patient died in the perioperative period, and other patients were discharged with normal liver and kidney function. Within the follow-up time of 22 to 88 months, these patients could live the normal lives with stable graft function and nutritional status. CONCLUSIONS Liver transplantation is the most efficient treatment for unresectable and symptomatic benign lesions, with the favourable outcome.

Abstract
The aim of this study was to analyze the incidence and risk factors of de novo HBV infection in pediatric patients receiving living donor liver transplants (LDLT) from HBcAb-positive donors, and to explore its treatment strategies. The data of 101 pediatric recipients receiving LDLT in Tianjin First Central Hospital between September 2006 and December 2012 were retrospectively analyzed. The HBV markers were regularly tested before and after the surgery, including HBsAb, HBsAg, HBeAg, HBeAb, and HBcAb. The median follow-up period was 25.6 months, during which eight cases (7.92%) were diagnosed with de novo HBV infection. Forty-four (43.6%) of the children received HBcAb-positive allografts. The rate of de novo HBV in the children that received HBcAb+ livers vs those received HBcAb- livers was 15.9% (7/44) vs 1.7% (1/57) (P=.037). The rates of de novo HBV in the children who received HBcAb-positive allografts were significantly less than in those that received preventative therapy with HBIG and lamivudine treatment (2/31, 6.4%) vs those that did not (5/13, 38.5%) (P<.01). HBcAb-positive liver donors are strongly associated with de novo HBV in HBsAg-negative pediatric patients receiving LDLT. However, the incidence of de novo HBV infection is significantly less with the use of prophylactic treatment strategies.

Abstract
Here we explore the T-lymphocyte suppressive and immunomodulatory effects of bone marrow mesenchymal stem cells (BMMSCs) overexpressing heme oxygenase-1 (HO-1) on acute rejection following reduced-size liver transplantation (RLT) in a rat model. The proliferation activity, cell cycle progression, secretion of proinflammatory cytokines, expression of CD25 and CD71 in lymphocytes, and activity of NK cells were found to be significantly lowered, and the proportion of regulatory T cells (Tregs) was found to be increased relative to BMMSCs when Adv-HO-1/BMMSCs were co-cultured with Con A ex vivo; secretion of anti-inflammatory cytokines was significantly higher. When treated with saline, BMMSCs or Adv-HO-1/BMMSCs, post-transplantation rats receiving Adv-HO-1/BMMSCs showed better median survival time, lower rejection activity index, higher anti-inflammatory cytokine levels, lower proinflammatory cytokine levels, more peripheral Tregs, and lower natural killer cell viability. These results suggest that HO-1 enhanced and prolonged the effects of BMMSCs on acute rejection following RLT, with immunomodulatory effects in which adaptive and innate immunity, as well as paracrine signaling, may play important roles.

Abstract
AIM To determine whether diabetes mellitus (DM) affects prognosis/recurrence after liver transplantation (LT) for hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC).
METHODS A retrospective study was conducted between January 2000 and August 2013 on 1631 patients with HBV-related HCC who underwent LT with antiviral prophylaxis. Patient data were obtained from the China Liver Transplant Registry (https://www.cltr.org/). To compare the outcomes and tumor recurrence in the HBV-related HCC patients with or without DM, statistical analyses were conducted using χ2 tests, Mann-Whitney tests, the Kaplan-Meier method, log-rank tests and multivariate step-wise Cox regression analysis.
RESULTS Univariate analysis of 1631 patients who underwent LT found overall 1-, 3- and 5-year survival rates of 79%, 73% and 71% respectively in the DM patients, and 84%, 78% and 76% in the non-DM patients respectively. Overall survival rate differences after LT between the two groups were significant (P = 0.041), but recurrence-free survival rates were not (P = 0.096). By stratified analysis, the overall survival rates in DM patients for age > 50 years (P = 0.002), the presence of vascular invasion (P = 0.096), tumors ≤ 3 cm (P = 0.047), two to three tumor nodules (P = 0.007), Child-Pugh grade B (P = 0.018), and pre-LT alanine aminotransferase levels between 40 and 80 IU/L (P = 0.017) were significantly lower than in non-DM patients. Additionally, serum α-fetoprotein level > 2000 ng/mL (P = 0.052) was associated with a significant survival difference trend between DM and non-DM patients. Multivariate analysis showed that the presence of DM (P < 0.001, HR = 1.591; 95%CI: 1.239-2.041) was an independent predictor associated with poor survival after LT.
CONCLUSION HBV-related HCC patients with DM have decreased long-term overall survival and poor LT outcomes. Prevention strategies for HCC patients with DM are recommended.

Abstract
Purpose Clear delineation between tumors and normal tissues is ideal for real-time surgical navigation imaging. We investigated applying indocyanine green (ICG) fluorescence imaging navigation using an intraoperative administration method in liver resection. Methods Fifty patients who underwent liver resection were divided into two groups based on clinical situation and operative purpose. In group I, sizes of superficial liver tumors were determined; tiny tumors were identified. In group II, the liver resection margin was determined; real-time navigation was performed. ICG was injected intravenously at the beginning of the operation; the liver surface was observed with a photodynamic eye (PDE). Results Liver resection margins were determined using PDE. Fluorescence contrast between normal liver and tumor tissues was obvious in 32 of 35 patients. A boundary for half the liver or specific liver segments was determined in nine patients by examining the portal vein anatomy after ICG injection. Eight small tumors not observed preoperatively were detected; the smallest was 2 mm. Conclusions ICG fluorescence imaging navigation is a promising, simple, and safe tool for routine real-time intraoperative imaging during hepatic resection and clinical exploration in hepatocellular carcinoma, enabling high sensibility for identifying liver resection margins and detecting tiny superficial tumors.
